Q:  What can you do if you disagree with your assessment?

A:  1. Contact MPAC 

They are there to answer your questions. If you think your assessment is incorrect, please call them toll free at 1-866-296-6722 to verify details about your property. 

You can also visit them at www.mpac.ca and click on the AboutMyProperty link. 

2. Ask MPAC to review your assessment 
If you believe your assessment is incorrect, MPAC will be pleased to further review your assessment through a Request for Reconsideration (RfR). There is no fee for an RfR and your request may be made any time before March 31 of the tax year. 
RfR forms are available on their web site, www.mpac.ca, or by calling them toll free at 1-866-296-6722. You may also write a letter requesting a reconsideration of your assessment. Please include the following information in your letter: your 19-digit roll number; your full name, address and phone number; and all the reasons why you feel your assessment is incorrect. 

To assist MPAC's review, it is necessary that you provide specific details about your property that support your concerns. The more information you provide, the quicker and easier it will be for MPAC to perform a review on your behalf. 

3. File a formal appeal if you still disagree with your property assessment 
Another option is to file a formal appeal with the Assessment Review Board (ARB) by March 31 of the tax year. The ARB is an independent tribunal of the Province of Ontario. Both the property owner and MPAC will be asked to appear at a hearing to present evidence to support their arguments. 

There are specific application forms and associated fees with this approach. An appeal can be launched before, during or after RfR has been submitted but must be withdrawn if an RfR successfully deals with your concerns prior to an appeal hearing. Similarly, an RfR will not be processed if an appeal has been heard by the ARB. 

To find out more about assessment appeals please visit the ARB's web site, www.arb.gov.on.ca, or call their toll free number at 1-800-263-3237 or 416-314-6900.
